This study will assess the impact of a family-based and community centered multilevel behavioral intervention addressing nutrition and physical activity with high risk parent-preschool children dyads to promote pediatric obesity prevention. The 7 year study will follow 600 parent preschool child dyads, half of whom will be randomized into the intervention condition which will utilize a health literate approach, build new social networks, utilize behavior modification tools including goal setting, self monitoring, and problem solving, and create behavior-environmental synergy with cues to action for use of the built environment for healthy behaviors. Both the intervention and control group (separately) will receive the control condition in which parent-child dyads will receive a literacy promotion/school success curriculum.
